an interesting commentary by Thom Hogan
A lot and not much. I'll use a different product to illustrate my point: the Apple iPad.
At the heart of an iPad is something labelled the Apple A4. This is a chip manufactured for Apple by Samsung, using technologies licensed by Apple from ARM. Over the years, Apple combined its own internal processor R&D with several small processor performance tweaking companies, and that group is responsible for the actual layout of the A4 chip. But Apple didn't design the CPU cores nor they actually manufacture chips. So, what is that chip? A Samsung? An ARM? Or an Apple?
